No, your solution starts with h=25cm, but the question says that h=24cm.

So, looking at one-half of the isosceles triangle, x

So, looking at one-half of the isosceles triangle, x

^{2}+ 24^{2}= (32-x)^{2}solves to x=7cm, which gives the area of the isosceles triangle as 7x24 = 168cm^{2}Tips to related online calculators
